As we’ve noted previously, Yahoo (YHOO) CEO Marissa Mayer is not messing around when it comes to getting her new company up to speed with her former employer, Google (GOOG). And now, unnamed sources have told Business Insider that Mayer has delivered a new ultimatum for employees working on product pitches: Figure out a way to get it out the door in six months or don’t bother pitching it at all. What’s more, Yahoo will no longer consider investing in any project “if it doesn’t have a realistic shot of reaching 100 million users or generate $100 million toward the company’s top line.”
